Simplify this please 2 7/8 - 4 3/8
nalin [4]

Answer:

The answer is -1 1/2

Step-by-step explanation:

This problem doesn't have that much steps.

What you do is this.

Step 1: You have 2 7/8 and 4 3/8 now turn it into a improper faction it will look like this 23/8 -35/8

Step 2: Now minus 23/8 and 35/8 23-35= -12 and the 8's stay the same now it will look like this -12/8

Step 3: Now see how many times 8 can go into -12 so -8 times 1= -8 now get from -8 to -12 that equals 4 so it will look like this -1 4/8 that can be simplify by 4 because 4x1=4 And 4x2=8 Now your answer is -1 /12
